Random surge of bots in my comments

As of yesterday every day at 7am I get “attacked” by a ton of bot comments on my page that do nothing but repeat what other comments have said. They’re extremely annoying and was wondering if anyone else has dealt with this/knows how to fix? I’ve never bought followers or anything so I’m very confused 🫠 they all have like the same posts when I look at their account and all have the yumleaks vote even though I don’t have a poll up?
